Exactly....
I tried to redo some calibration of the quiescent current and the
filters to peak the linearity, and now the problem is gone. Now the
signal is perfect in 144 MHz also.
Now the only thing to solve is about the PTT, and we are ready to give
it a fight for the VHF contest of march.... but this is Wayne's field so
I'll let him work on that without stressing him too much..... ;-)
Tnx and 73 de Giulio IW3HVB
